Given that my technical background is largely in the networking space (exhibit A, exhibit B, exhibit C(CIE)), one of the first things I tried to wrap my head around when being introduced to AWS is how networking works in the AWS cloud.

What I attempted to do was build a mental model by relating cloud networking constructs such as Virtual Private Cloud (VPC), subnets, and routing tables to on-prem, physical networking constructs. This worked pretty well but I did get tripped up at times because some of these constructs don’t map exactly one-for-one.

This post will explain the mental model I used while also calling attention to the elements or behaviors that don’t map exactly between on-prem and AWS.
